ANTISKIID DEVICE.

Z all whom it may concern:

\ a specification.

This invent-ion relates 'to anti-skid devices for automobile tires and the like and its novelty consists in the construction and adaptation of the parts as will be more fully hereinafter pointed out.

.The chain systems commonly employed for this purpose have several disadvantages. One is the large number of joints making as many points of weakness; a second is the tendency'of a chain to break and become loose at one end,-the reafter tapping against the mud guard of the vehicle untiltaken up'or removed; a third is the number of "places liable to deterioration and repair under usual conditionsof use; and another,

and most important, is that the presence of a chain does not prevent, or materially lessen, the tendency to side slip or lateral skidding, especially when the vehicle is traveling on a highway with a relatively high crowned road surface.

'My invention has for its object the over coming of'the disadvantages referred to and to that end it is so constructed that it has comparatively few parts and joints and corrects the tendencyi'o side skidding.

In the drawing, Figure 1 isa miniature view of a tire showing a device embodying my invention applied to a portion of its surface; Fig. 2 is aside elevation of a portion of'a tire to which the invention has been applied; Fig. 3. is a section on the plane of the line 33 in Fig.2; Fig. 4 is a plan view ,of the parts shown in Fig. 2; Figs. 5 and 6 are perspective views of the links; and Fig. 7 is a plan of the bahd. In the drawings, 10 is an automobile tire ofusual forrin. 20 is a band made preferably of flexible metal and formed of a series of loops alternately reversed, one with respect to the other and gradually increasing in width from each end of the band c0nsidered as a whole toward the middle, forming Specification of Letters Iaterit.

terruptions, and that it is bent into wide curves 22 preferablycircular in. outline and without straight portions running transversely across the tire buthaving sectionsor portions disposed in a general longitudinal direction which counteract the tendencv to side skiddin v The multlple bands 20 are arranged atv suitable intervals around the tire and are connected together by any suitable means.

I prefer, however, to use links 23 of a specific form, each composed of a single piece of metal having hooked extremities de-. signed to engage one or more of the loops of each band and at the opposite end of the links bent into shape to form a, hook 24 and eve This connecting means may be supplanted by or supplemented by sections of chain 26 connectingthe ears 21 of the bands 20.

What I claim as new is:

1. Ananti-skid device for automobile tires and the like, comprising a. series of multiple reversed loop bands arranged around the tire and connected together by intermediate links. 1 I

2. An anti-skid device for automobile tires comprising a series of bands adapted to transversely. encircle the tire each band comprising a plurality of loops extending from side to side of the bandalternately reversed in position.

a 3. An anti-skid'device for automobile tires and the like, comprising a series of multiple reversed loop bands. arranged around the tire, each band terminating in a ring-like loop on each side, the successive bands being connected together by' chain members engaging the loops.

4:. An anti-skid device for automobile tires comprising a series of bands adapted totransversely encircle the tire each band comprising a plurality of loops extending from side to side of the band alternately reversed in position and each band terminatingin a ring like loop, and links connecting the loops of adjacent bands.

5. A band for an anti-skid device con prising a series of multiple curved loops, each loop being reversed with respect to the one nextto it, and-the loops gradually decreasing in size from the middle toward each end of the band.

one next toit and being formed of substan t-ially circular arcs, and the loops gradually decreasing in size from the middle toward each end of the band. a

8. An anti-skid device for automobile tires comprising'bands made up of a seriesv of alternately reversed loops formed in circular arcs, and which bands are connected together around the tire by intermediate links.

9.'Anl anti-skid device for automobile tires comprising bands made. up of a series of alternately reversed circularly curved loops gradually deereasing in Width frprn the middle toward each end of the band, and which bands are connected together around the tire by intermediate links;
